Overview of this book

Always dreamed of creating your own games? With the third edition of Beginning C++ Game Programming, you can turn that dream into reality! This beginner-friendly guide is updated and improved to include the latest features of VS 2022, SFML, and modern C++20 programming techniques. You'll get a fun introduction to game programming by building four fully playable games of increasing complexity. You'll build clones of popular games such as Timberman, Pong, a Zombie survival shooter, and an endless runner. The book starts by covering the basics of programming. You'll study key C++ topics, such as object-oriented programming (OOP) and C++ pointers and get acquainted with the Standard Template Library (STL). The book helps you learn about collision detection techniques and game physics by building a Pong game. As you build games, you'll also learn exciting game programming concepts such as vertex arrays, directional sound (spatialization), OpenGL programmable shaders, spawning objects, and much more. You’ll dive deep into game mechanics and implement input handling, levelling up a character, and simple enemy AI. Finally, you'll explore game design patterns to enhance your C++ game programming skills. By the end of the book, you'll have gained the knowledge you need to build your own games with exciting features from scratch.

Collision Detection, Pickups, and Bullets

So far, we have implemented the main visual aspects of our game. We have a controllable character running around in an arena full of zombies that chase them. The problem is that they don’t interact with each other. A zombie can wander right through the player without leaving a scratch. We need to detect collisions between the zombies and the player.

If the zombies are going to be able to injure and eventually kill the player, it is only fair that we give the player some bullets for their gun. We will then need to make sure that the bullets can hit and kill the zombies.

At the same time, if we are writing collision detection code for bullets, zombies, and the player, it would be a good time to add a class for health and ammo pickups as well.

Here is what we will do and the order in which we will cover things in this chapter:

  • Coding the Bullet class
  • Making the bullets fly
  • Giving the player a crosshair...
